IMPROVEMENT lN FLUID-METERS.

Specification forming part of Letters Patent No. 125,805, dated April16, 1872.

To all whom it may concern:

Be it known that I, J oHN HARTMANN AU- GUST GERIGKE, of Hoboken, in thecounty of Hudson and State of New Jersey, have invented a new and usefulImprovement in Fluid- Meters; and I do hereby declare the following tobe a full, clear, and exact description thereof, which will enable thoseskilled in the art to make and use the same, reference being had to theaccompanying drawing forming part of this specification, in whichdrawing- Figure 1 represents a vertical central section of my meter.Fig. 2 is a plan or top view of the same.

The remaining figures are details, which will be referred to as thedescription progrosses.

Similar letters indicate corresponding parts.

This invention relates to an improvement on that class of fluid-metersfor which a patent was granted to Leopold F. Buschmann, January 17,1871, No. 111,040; and it is intended particularly to facilitate theconstruction of this meter, and also to reduce the friction of the fluidpassing through it. My improvement consists in the arrangement of twoelbows, which are provided at their inner ends with flanges for thepurpose of being fastened together, one of said elbows being 7 bored outto receive the guide-curves and the other to receive a turbine orreaction waterwheel, which is mounted on a shaft that has its bearing atone end in a socket in the hub of the stationary-guide curves, while itsother end extends through a tube projecting from the inner surface ofthe second or discharge elbow, and provided with a stuflin'g-box in sucha manner that the guide-curves, as well as the turbine-wheel, can bereadily fitted into their places, and that by separating the elbows easyaccess can be had to said parts for the purpose of cleaning orrepairing; and, furthermore, by the curvatures of the two elbows, thefluid flows to and from the guidecurves and turbine-wheel with the leastpossible friction,while the tubular projection of the discharge-elboweffectually prevents leakage. The supply-elbow is provided with astop-cock to regulate or close the supply of fluid to the meter, as maybe desired.

In the drawing the letter A designates the supply-elbow, and the letterB the dischargeelbow. These elbows are provided at their inner ends withflanges a b, which are faced off, so that when the same are fastenedtogether by means of screws 0 a tight joint will be produced betweenthem. The inner end of the supply-elbow is bored out to re ceive theguide-curves O, detached views of which are shown in Figs. 3, 4, and 5,Fig. 3 being a view of one face, Fig. 4 a side view, and Fig. 5 a viewof the opposite face of the same. These guide-curves are dropped intothe socket provided for them in the end of the supply-elbow, and theyare held in place by screws d. The inner end of the dischargeelbow B isbored out to receive the turbine or reaction wheel D, detached views ofwhich are shown in Figs. 6, 7, and 8, where Fig. 6 represents a plan orface view of the wheel, Fig. 7 is a transverse section of the outerring, Fig. 8 is a detached side view of the hub or body of the wheel.This wheel is mounted on a spindle. E, which has its bearing at one endin the hub or body of the guide-curves, while its other end extendsthrough a tube, F, cast solid with the discharge-elbow and projectingfrom the inner surface thereof, as shown in Fig. 1. This tube isprovided with stufflng-boxes f 9, one in each end, and by filling thesestuffing-boxes with suitable packing-pieces the leakage of the fluidthrough said tube-is prevented. On the spindle E is mounted a worm, G,which transmits the motion of the turbine-wheel to the registeringapparatus. In the supply-elbowA is arranged a stop-cock, H, which servesto shut off the fluid or to regulate the supply. By combining the twoelbows A B with the guide-curves O and turbinewheel D, the fluid to bemeasured is conducted to and from the wheel with the least possiblefriction; and by enabling the fluid to exert its full power (or nearlyso) on the wheel, I have produced a meter which gives a correct resultindependent of the head under which the fluid is made to pass throughthe meter or of the velocity of said fluid; and, furthermore, bysecuring the guidecurves in the end of one elbow and the wheel in theend of the other elbow easy access can be had to those parts simply byseparating the two eltialiy in the manner herein shown and debows.scribed.

What I claim as new, and desire to secure This specification signed byme this 7th day by Letters Patent, is-- of February, 1872.
